- Abstract
- Traces the development of online catalogs in the USA that feature subject searching and browsing through the machine-readable text of library classifications. Covers the author's experiences from 1983-86 developing and testing subject searching and browsing capabilities in an experimental online catalogue using the machine-readable 19th edition of the DDC. Suggests improvements to the original subject searching and browsing capabilities in the experimental online that would enable users to search and browse the DDC tables

- Abstract
- The first studies of online catalog use demonstrated that the problems of too many and too few retrievals plagued the earliest online catalog users. Despite 15 years of system development, implementation, and evaluation, these problems still adversely affect the subject searches of today's online catalog users. In fact, the large-retrievals problem has grown more acute due to the growth of online catalog databases. This paper explores the use of library classifications for consolidating and summarizing high-posted subject searches and for handling subject searches that result in no or too few retrievals. Findings are presented in the form of generalization about retrievals and library classifications, needed improvements to classification terminology, and suggestions for improved functionality to facilitate the display of retrieved titles in online catalogs
